|

|
|
<div><p>Collects more detailed information about a specific application,
|
||
|
|
program or system resource, and provides detailed insight into a specific
|
||
|
|
performance problem. This includes the capability both to perform several
|
||
|
|
types and levels of traces and to run detailed reports.</p>
|
||
|
|
<p>Performance explorer is a data collection tool that helps the user identify
|
||
|
|
the causes of performance problems that cannot be identified by collecting
|
||
|
|
data using Collection Services or by doing general trend analysis. Two reasons
|
||
|
|
to use performance explorer include:</p>
|
||
|
|
<ul><li>Isolating performance problems to the system resource, application, program,
|
||
|
|
procedure, or method that is causing the problem</li>
|
||
|
|
<li>Analyzing the performance of applications</li>
|
||
|
|
</ul>
|
||
|
|
<p>The collection functions and related commands of performance explorer are
|
||
|
|
part of the <span class="keyword">i5/OS™</span> licensed
|
||
|
|
program. The reporting function and its associated commands are part of the
|
||
|
|
base option in the Performance Tools for <span class="keyword">iSeries™</span> licensed
|
||
|
|
program and therefore, are available with either the Manager feature or the
|
||
|
|
Agent feature. The AS/400<sup>®</sup> Performance Explorer Tips and Techniques book
|
||
|
|
provides additional examples of the performance explorer functions and examples
|
||
|
|
of the enhanced performance explorer trace support.</p>
|
||
|
|
<p>Performance explorer is a tool that helps find the causes of performance
|
||
|
|
problems that cannot be identified by using tools that do general performance
|
||
|
|
monitoring. As your computer environment grows both in size and in complexity,
|
||
|
|
it is reasonable for your performance analysis to gain in complexity as well.
|
||
|
|
The performance explorer addresses this growth in complexity by gathering
|
||
|
|
data on complex performance problems.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Performance explorer is the tool you need to use after you have tried
|
||
|
|
the other tools. It gathers specific forms of data that can more easily isolate
|
||
|
|
the factors involved in a performance problem; however, when you collect this
|
||
|
|
data, you can significantly affect the performance of your system.</div>
|
||
|
|
<p>This tool is designed for application developers who are interested in
|
||
|
|
understanding or improving the performance of their programs. It is also useful
|
||
|
|
for users knowledgeable in performance management to help identify and isolate
|
||
|
|
complex performance problems.</p>
